This paper solves the visual cryptography problem by the Blakley scheme that is a geometry-based secret sharing strategy. We first partition the protected image into non-overlappi...
Presentation
The Discrete Pascal Transform (DPT) has been proved remarkably useful for edge detection, filter design, discrete-time signal interpolation and data hiding. In the present work a n...
